A look at the show’s unique HDR look and workflow

Each Mindhunter hour-long show (from the 10-episode run) was graded using FilmLight’s Baselight color grading tools by colorist Eric Weidt, who navigated between ultra-modern capture technology, the time and place of late 70s cinema and the very specific needs of David Fincher.
Adding an editorial and visual effects team at his facility in Hollywood, Mindhunter was the first time that the auteur established his own in-house DI. “It’s important to note, we had a lot more time to work on this show than most grades,” Weidt pointed out during a special HDR presentation by FilmLight, Dolby, and Red Digital Cinema at Hollywood’s Dolby Cinema Old Vine theatre.
“The 70’s and serial killers backdrop brought to mind David Fincher’s Zodiac, which is an absolutely brilliant movie; a masterpiece in terms of both content and color,” he says. “The 70s has a distinct color palette” he continues. Street photographers William Eggleston and Stephen Shore are personal sources of inspiration for initial color grading.
Post and edit began as production rolled in Pittsburgh. Dailies were usually available to Fincher by the following day. The production used FotoKem’s nextLAB dailies system and the PIX asset and data management and delivery platform.
Due to overlapping shoot and post production schedules, “David looked at things on his iPad for two-thirds of the season,” says Weidt, explaining that he had a complex rendering process that allowed him to manage new HDR footage as well as sending regular corrections from Fincher to view in SDR. The Baselight workflow file was separated into two timelines, one for any creative color adjustments, and another that had stabilizations and lens emulations applied. Weidt would daisy-chain them, run it through the Dolby Vision HDR professional tools, and create offline files to view on an iPad or monitor.
Weidt says that Fincher’s color design for Mindhunter was heavily influenced by the organic palette of several classic films, such as McCabe and Mrs. Miller, All the President’s Men and the more chromatic yet grittier look of The French Connection. They also wanted a low contrast, information-rich picture, and had first experimented with low contrast optical filtration on set but preferred in the end to “set up the digital chain in a way that Fincher was getting the type of image that he wanted.
Weidt’s starting point for dailies, as well as any color work on the master, began with a low-contrast log curve that maintained as much of the dynamic range provided by the Red Xenomorph camera as possible, and gave the SDR monitoring on set an approximation of Weidt’s HDR workflows.
The HDR look was developed in post production: “In HDR, we initially came across a lot of scenes where the light sources were taking too much prominence,” Weidt says. “David and his post supervisor Peter Mavromates really wanted an elegant balance. Mindhunter’s HDR is not trying to strike you or slap you in the face. Just like the sound mixing, or cutting, it is not trying to blow your mind, but rather convey the story content. The latter is really what’s going to punch you.”
Many of Fincher’s notes require simple dodging and burning, performed primarily through Weidt’s use of shapes, masking and tracking in Baselight. Using PIX, Fincher would circle subjects or areas of a frame, giving suggestive chromatic terms like ‘sallow’ or ‘ruddy,’ and ‘equidistant’ or ‘symmetrical’ in regard to reframing.

After the grade
“David is famous for having a visual style where he is going to stabilize two-thirds of the shots in an episode, or in a movie, so that everything is absolutely perfect,” says Weidt. “What he wants is that the camera, the gaze into the image, is totally unconscious, and you’re really in there without distractions that most people take for granted.” After Fincher returned to Los Angeles, their standard workflow on a scene together would start with a master shot that incorporated the characters as well as background, timing color and light levels for other shots and angles in scenes to be timed from that reference.
Fincher’s eye for detail goes far beyond that, though, and Weidt noted several corrected items that would have escaped his attention, like plants outside a prison that were too vibrantly green, or highlights in reflections that needed to be turned down to match light sources. “There are certain colors that David needs to suppress, and that’s mostly pink,” he continues. “Pink appears in people’s skin tones, and if you get it wrong in the grading suite and ends up on a monitor outside of that environment, it’s going to appear like they have pink faces and it looks really bad. David wants to control that.”
Using Summilux-C primes from CW Sonderoptic, XML information was created for every focal length. This was a requirement on Mindhunter as simulations of grain, lens barreling and chromatic aberration in Baselight were tailored to the specific focal length throughout the show. Weidt even created anamorphic effects for the spherical lenses. “David wanted to refer to 70’s in what could be called ‘the anamorphic wide-screen era,’” he says.
He also added pseudo chromatic aberration “on every shot and every episode of Mindhunter,” which he developed himself, as the vast majority of plug-ins and filters will simply shift one of the primary color plates, stretching from center, resulting in bi-color aberrations. These created results that Fincher found lackluster, when for example given a cyan-red, he’d really only want the cyan. “I found the solution in Baselight, which essentially took 20 layers, using blending modes that are usually the purview of a compositing tool,” Weidt says.
“David directed four episodes of Mindhunter, but he’s the executive producer for the show, and he’s definitely the director of the DI,” he adds. “All of the color, he directed himself, with contributions from Erik Messerschmidt.”
